A&E Real Estate Holdings is in contract to pick up a five-building Brooklyn multifamily portfolio for $89 million, or $366 per square foot, sources told The Real Deal.

The buildings, which collectively span about 243,000 square feet, are scattered around Prospect Park – in neighborhoods such as Kensington, Prospect Lefferts Gardens and Prospect Park South. It contains 265 apartments, most of which are rent-stabilized.

A&E entered contract on the package last month and is expected to close on the purchase in either December or January, sources said. The price comes out to nearly $350,000 per unit. The going-in capitalization rate is about 5 percent, sources said.

An affiliate of John Streicker’s Sentinel Real Estate Corporation acquired each of the buildings separately from 2006 to 2008 for a total of $37.7 million, property records show.

The deal continues A&E’s multifamily acquisition spree, particularly in the outer boroughs. The Midtown-based firm owns more than 100 buildings in New York City and has amassed more than 8,800 rental units since forming in 2011, according to a TRD analysis. The firm’s heads are Douglas Eisenberg and John Arrillaga Jr., sons of Urban American Management CEO Philip Eisenberg and billionaire Silicon Valley developer John Arrillaga Sr., respectively.
